May 21, 2005 One of the aspects of convergence we didn’t see coming was the convergence of childrens bicycles and adult commuters. That’s what seems to be happening as the wildly popular Schwinn Sting-Ray bicycle is being upgraded with an electric motor. The new Sting-Ray Electric shares the original design characteristics of the Street Series Sting-Ray, but adds an electric motor and a battery pack in the form of a motorcycle engine casing so it looks even more like the chopper it originally emulated when it took the world by storm way back in the early sixties. The new Sting-Ray Electric will reach 14 mph and the battery will last up to two hours for a price of US$399. Those specs are distinctly commuter machine territory.
